ABSTRACT In this paper, a PWM scheme for three-level full-SiC uninterruptible power supplies (UPSs) has been developed to achieve a high power-density. Two key passive components have been selected for size reduction of the full-SiC UPS; common mode (CM) EMI filter...
ABSTRACT This letter proposes a novel wireless power transfer (WPT) system with repeater coils for multiple loads. Every two repeater coils form a repeater unit where one is used to receive power from its preceding unit and the other transmits power to the subsequent...
ABSTRACT This paper proposes an improved pulse density modulation (IPDM) power control method for semi-bridgeless active rectifier (SBAR) in inductive power transfer (IPT) system. In this method, the input voltage pulse sequences of the SBAR can be distributed more...
ABSTRACT In this paper the concept of an Optiverter is proposed as a novel class of photovoltaic (PV) module level power electronics systems. Functionally, the Optiverter is a hybrid technology that combines the ultrawide maximum power point tracking (MPPT) voltage...
ABSTRACT Solid-state transformer (SST) for onboard traction application is also addressed as power electronic traction transformer (PETT), which is used to replace the line frequency traction transformer (LFTT) and four-quadrant converter (4QC) to further improve...
ABSTRACT Power electronics based Medium-Voltage Direct Current (MVDC) Microgrids consist of several interconnected feedback-controlled switching converters. Such systems experience bus voltage stability challenges owing to the negative incremental resistance of...
